Rules for writers, Tenth edition - Diana Hacker, Nancy Sommers 2021

Check for correct word breaks when words must be divided at the end of a line
Hyphenation
Mechanics

Only words that already contain a hyphen should be broken at the end of a line of text. If your word processor automatically breaks words at the ends of lines, disable that setting.

Email addresses, URLs, and DOIs need special attention when they break at the end of a line of text or in bibliographic citations. Do not insert a hyphen. Instead, consult the guidelines for URLs and DOIs in MLA style (58a) and APA style (63a). Break an email address after the @ symbol or before a period.

EXERCISE 45-1

Edit the following sentences to correct errors in hyphenation. If a sentence is correct, write “correct” after it. Answers appear in the back of the book.

b. The swiftly-moving tugboat pulled alongside the barge and directed it away from the oil spill in the harbor.

c. The ice-encrusted fossil was a major find.

d. Your dog is well-known in our neighborhood.
